PUMP.

QBPECIFICATIQN 't'orining part of Letters Patent No. $78,766, dated February 28, 1868.

Application filed January 14,1886. Serial No. 188,5l0. (No model.)

To aZZ whom it mayeoncei'n:

Be it known that I, JAMES (J. CARTER, of the city ofDec-atur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Pumps, of which thefollowing is a specification.

My object is to produce a cheap and effective lift-pun1p that may by means of a simple adjustment be readily converted into a forcepump; and my invention consists in certain details of construction and combinations of parts, as hereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specification, Figure 1 isa vertical section of my pump-casing, showing the construction and arrangement of the rod and valves therein. Fig. 2 is a representation of the adjustable upper valve, and Fig. 3 is a vertical section of the same.

a is the casing forthe upper valve.

1) is an equalizing-chamber, provided with outlet 0.

(Z is the pump-handle, constructed in any well-known manner and suitably pivoted on the casing.

e is a pipe extending downward from chamber 11 to lower valve-casing, g.

fis a supporting-collar that embraces pipe 6 and rests on the top of the well-platform.

h is an ordinary bucket-valve in casing 9, attached to the lower end of the pump-rod.

2' is an ordinary flap-valve at the bottom of easing g.

It is a pipe that connects casing 51 with the water to be elevated.

Z is the piston-rod connected with the pumphandle by means of jointed red at.

a is an expansible valve on the upper end of rod Z.

r is a pivot-head for rod Z.

is a valve-supporting band, provided with corrugated surface 1) and holes g. This band is also provided with downwardly-projecting shoulder t, threaded externally and internally, and provided with peripheral recess or depres sion 8. The internal threads of the shoulder fit on the upper end of the pump-rod, the valve 12 fits in the depression 8, and collar it engages the external threads of the shoulder and secures the valve in position. The valve or, which is necessarily elastic, is forced over the external threads of the shoulder-into depression 8, and, after collar a is properly adjusted, is suitably locked to prevent misplacement.

o is a disk, made rigid with the piston-rod in any well-known manner at about the proportionate position shown, and beveled, as indicated, on the upper portion of its periphery.

When the pump-handle is at the lowest point ofitsstroke,the band 12 should rise above the top of the pump, and the valve a, in its normal condition, should be slightly smaller than the internal diameter of the casing, so that under ordinary circumstances the lower valve or bucket will operate alonein the man nor of a common lift-pump.

In order to convert the device into a force pump, band 0 is screwed down untilthe lower portion of valve or is expanded by the resisting pressure of beveled disk 1; to the diameter of the interior of easing 0, thus making said valve operative.

In operating the device as a force-pump the water is lifted by bucket-valve h and the downward pressure of the valve a is resisted by flap-valve '5. Chamber 1) increases the efficiency of the forcing mechanism by providing a reserve supply of water that has the effect of equalizing the flow.

l/Vhile the specific means shown and described for expanding the upper valve are considered preferable, it is obvious that the valve may be forced on the disk in a variety of well known ways, or that the disk may be forced into the valve, and consequently I do not wish to be understood as confining myself exclusively to therigid disk and threaded valve, as herein specified.

1. A convertible force and lift pump consisting in the combination of acylinder, means for supporting the cylinder on a well-platlorm, means for connecting the cylinder with the Water of the well, a lateral discharge-spout for the cylinder, a pivoting-handle for the eylin der, a piston-rod in the cylinder connected with the handle in a suitable manner, a liftvalve on the piston-rod below the dischargespout, a valve in the cylinder below the liftvalve on the piston-rod,an expansible inverted bucket valve screwed onto the piston-rod above the discharge-spout, and a bevel-edged spout, and an inverted bucket-valve screwed onto the threaded portion of the rod immediately over the disk, as and for the purpose set forth. r 5

In testimony whereof Isign my name in the presence of two subscribing witnesses.

JAMES C. CARTER.
